I'm a pumper for about six years; type 1 for 46 years. I'm 56.
Check out "frio" or its equivalent for keeping insulin cool.
Insulin pens are helpful. I injected through clothes on many occasions without ill effects.
I did break a pump falling on it. I now wear it around my neck on a lanyard under my jacket.
Check your Bg every hour or 90 minutes, especially for the first two days, to discover your rhythms.
Adjust accordingly.
being alone means maybe running a bit high at bedtime lest you run into lows at night.
It's really no big deal.
Good luck. Be smart. Don't worry.
